I have just been involved in a conversation with a retired engineer,
who was talking about engineers 'wheeching' along 33 kV lines in a
Faraday cage. Somebody asked what a Faraday cage was and I commented
that it was okay to touch it from inside. The engineer said it
certainly was not. I thought the point was that everything was at the
same potential and therefore safe. Who was right?

Give it a try :-)

Was the EHT generated at varying frequencies to match the notes for each
time he caused an arc, or has the sound been dubbed on afterwards?

The tesla coils are modulated by an audio feed, there's enough videos of them
about, and DIY kits available ...

I only know that faraday cages are supposed to block RF and to offer a path
to ground for stuff like lightening. As to what you do if you are working on
cables inside it really depends on a lot of variables. If its the same
potential as the cable then the protection for those outside and the
earthing are null and void terms.
Like many things in this world it much depends on the use you are putting
it to. When the engineers work on overhead lines they seem to wear suits and
have a special clip so they and the cable are at the same potential, but is
that not similar to what happens on a smaller scale to all those meter
changers and those installing new line fuses in certain sorts of
installations.

Does anyone remember those stage electric acts where sparks were
everywhere, one assumes huge voltages but not much current. They used to
get young ladies to come up and stand on a pad and make her hair stand on
end and have a violet glow around her.

All good clean fun.
However in the real world you just have to watch out for the potential
difference, since nobody wants to become a human resistor.

Yes somewhat impractical as a musical instrument, too many variables like
moisture in the air affecting when the spark wiwill occur I remember seeing
a plasma tweeter once. That had a loudish fizz with the audio.

Some women show no resistance at all.
